Procedure

In an analogous manner to that described in Example 1(g), by alkylating tert-butyl (3RS,4RS)-4-(4-allyloxy-phenyl)-3-hydroxy-piperidine-1-carboxylate [Example 86(b)] with 2-chloromethyl-1-(2-methoxy-ethoxy)-naphthalene [Example 122(h)] there was obtained tert-butyl (3RS,4RS)-4-(4-allyloxy-phenyl)-3-[1-(2-methoxy-ethoxy)-naphthalen-2-ylmethoxy]-piperidine-1-carboxylate, from which by cleavage of the allyl group by means of bis-(triphenylphosphine)-palladium(II) diacetate analogously to Example 152(e) there was obtained tert-butyl (3RS,4RS)-4-(4-hydroxy-phenyl)-3-[1-(2-methoxy-ethoxy)-naphthalen-2-ylmethoxy]-piperidine-1-carboxylate. Subsequent alkylation with 3-phenyl-isoxazol-5-ylmethyl methanesulphonate analogously to Example 44(e) gave tert-butyl (3RS,4RS)-3-[1-(2-methoxy-ethoxy)-naphthalen-2-ylmethoxy]-4-[4-(3-phenyl-isoxazol-5-ylmethoxy)-phenyl]-piperidine-1-carboxylate as a colourless solid; MS: 665 (M+H)+.
